Japanese Professor Creates Glasses to Disrupt Facial Recognition

To the average person, facial
recognition is a nice feature. It helps you autofocus more accurately
and it lets you tag your friends more quickly on Facebook. Professor
Isao Echizen isn't a fan though, and expresses concern that facial
recognition can be used to invade privacy.

As a response to the tech, he's created
glasses that utilize infrared LEDs to prevent cameras from being able
to recognize a face. The infrared light, while invisible to humans,
shows up as a bright purple on CMOS and CCD sensors.

The glasses Echizen has created aren't
exactly stylish, or subtle, but they could easily be a stepping stone
on the way to giving people a bit more privacy.
